Thermal insulation performance: achieved inside the furnace200℃, the outer wall temperature does not exceed (room temperature)+20℃). Test point: at least away from the inner liner material 100 Millimeters, at least for doors120Millimeters.

Test time: After reaching the set temperature (constant temperature state) 15minute. Operating noise: ≤70db;The above indicators are all under normal pressure and no-load conditions, with a distance from the inner wall of the box1/6Testing within the space;

3、 Box structure:

Adopting a combination of dual side air ducts and top air duct circulation,Double door design, the door buckle is fixed with a containerized sheep horn handle or chrome plated spring door handle, and sealed with a high-temperature resistant sealing strip,Install iron feet or wheel foot cups to support the bottom four corners.

Interior wall material of the studio: all made of high-quality materialsA3Made by bending cold-rolled steel plates, locally reinforced with groove shapes on the inner side to avoid thermal deformation.

Air duct materials: all made of high-quality materialsA3Cold rolled steel plate punching plum blossom shaped holes, sheet metal bending and fixing. The overall surface of the workspace is sprayed with bright high-temperature resistant silver powder paint for rust prevention treatment (can withstand)500High temperature does not peel off or change color.

External material: Made of high-quality materialsA3Made by bending and welding cold-rolled steel plates, and then sprayed with environmentally friendly high-temperature resistant metal hammer paint (silver gray,The color can be customized according to customer requirements.

Box skeleton: adopts5#Angle steel, partially used10#Channel steel reinforced sheet metal welding reinforcement. Enhanced Framework: Adopting10#Channel steel4#and5#Angle steel, partially welded with groove reinforced sheet metal.

Insulation material:120KHigh density aluminum silicate fiber filling with insulation layer thickness of100mm.

4、 Circulating system:

Hot air circulation method: The workspace is equipped with left, right, top or bottom three sided circulation air ducts with a high-pressure air circulation system and horizontal laminar air supply on both sides. The internal hot air circulation method of the oven is to blow hot air from the right side of the working room, and then return it to the left side of the working room for repeated circulation. The hot air is regularly blown to every corner of the working room to achieve uniform temperature inside the working room.

Another circulation method: The workspace is equipped with left, right, and top three sided circulation air ducts with a high-pressure air circulation system and a combination of left and right horizontal and vertical air supply. The internal hot air circulation method of the oven is to blow hot air from the left and right sides of the working room, and then return the air from the top of the working room to circulate repeatedly, in order to achieve uniform temperature inside the working room (the left and right sides of the working room are fully covered with perforated plates, which is conducive to the uniform inflow and outflow of circulating air).

Hot air circulation fan: The high-temperature resistant long shaft blower motor is installed externally at the top (or lower left side) of the box, with the long shaft penetrating into the air duct at the top (or lower left side) of the working chamber, and equipped with a multi wing high air volume centrifugal silent fan wheel for blowing.

The top of the oven is equipped with an adjustable exhaust valve, which facilitates the discharge of exhaust gas and water vapor. Customers can connect external pipelines to the outside.

5、 Electrical system:

Electrical control box: It adopts independent hanging or integrated control box, installed on the side of the machine, and can be selected from left and right;

Temperature control device: adopts microcomputer intelligent temperature controller, with dual row controllerLEDdigital display/P. I.Dcontrol/Automatic calculation/Film button setting/Control accuracy ±1%FS.

The over temperature alarm will activate a buzzer alarm when the temperature inside the box reaches the set limit temperature value, and automatically cut off the heating until the temperature returns to normal. The alarm state will be automatically released and the alarm will continue to work.

Temperature measuring device: Both the intelligent temperature controller and the over temperature protection device are made of stainless steel armorPT100Platinum resistance (orKThermocouple temperature sensing device with precise temperature measurement and long service life.

Timed alarm device: using digital display0~9999(Time)/divide/Four digit switchable in secondsLEDWhen the temperature inside the oven reaches the set value of the main control instrument, the timer will automatically start counting. When the time reaches the set value, the red sound and light alarm will automatically sound to indicate the end of the work (the alarm can be manually switched on or off). If you want to continue heating after the timer ends, you need to restart the timer.

6、 Comprehensive security measures:

The main circuit is equipped with grounding devices, overload, overcurrent, short circuit, and protection devices. The fan control circuit is equipped with overload, overheating, and phase loss protection devices, which automatically protect the motor in case of abnormal conditions.

7、 Equipment usage conditions:

Environmental conditions: Temperature-5～40℃； Humidity ≤85%R.H; Electricity Source:AC380VOr single-phase220V 50HZThree phase five wire system,(Can provide power sources for various countries, such as110V/220V/380V/415V/440V…(50/60)Hz）

No strong vibration, no strong magnetic field influence, no corrosive gas;
